Detailed explanation-1: -Radioisotopes are radioactive isotopes of an element. They can also be defined as atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus.
Detailed explanation-2: -Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table.
Detailed explanation-3: -For example, carbon-14 is a radioactive isotope of carbon that has six protons and eight neutrons in its nucleus.
Detailed explanation-4: -Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
